Electronic technology is an emerging technology developed from the end of the 19th century to the beginning of the 20th century. It has developed rapidly and been widely used in the 20th century, and has become an important symbol of the development of modern science and technology. At the end of the 18th century and the beginning of the 19th century, due to the needs of production development, the research on electromagnetic phenomena developed rapidly. In 1785, French scientist Coulomb obtained the Coulomb law of current through experiments. In 1895, Dutch physicist Hendrick Anton Lorenz assumed the existence of electrons. In 1897, the British physicist j.j.thompson found the electron by experiment. In 1904, the British j.a.fleming invented a simple diode (diode or valve) to detect weak radio signals. In 1906, l.d.forest installed a third electrode (grid) in the diode and invented the triode with amplification function, which is an important milestone in the early history of electronics. In 1948, several researchers at Bell Laboratories in the United States invented the transistor. In 1958, samples of integrated circuits appeared in the world. The emergence and application of integrated circuits marks a new stage in the development of electronic technology.
Electronic technology studies the application of electronic devices and circuits composed of electronic devices. Semiconductor devices are the basic components of various discrete and integrated electronic circuits. With the rapid development of electronic technology, various new semiconductor devices emerge in endlessly. The development direction of modern power electronics technology is from traditional power electronics, which mainly deals with problems with low-frequency technology, to modern power electronics, which mainly deals with problems with high-frequency technology. Power electronics technology began with silicon integration in the late 1950s and early 1960s

The development of current devices has experienced the era of rectifier, inverter and frequency converter, and promoted the application of power electronics technology in many new fields. The power semiconductor composite devices developed in the late 1980s and early 1990s, represented by power MOSFET and IGBT, which integrate high frequency, high voltage and high current, show that the traditional power electronics technology has entered the modern power electronics era.
